私は一日の大半を机に頭をぶつけていて、一生これを理解することができません。明らかにグローバル アプリケーション キャッシュにあるアセンブリが、それを使用しようとしている Web アプリによって検出されません。私がウェブ上で見つけることができるものはすべて、GAC からの読み込みを回避する方法がないことを前提としているか、明示的に述べています。これはグローバルで必須の動作です。それでも、私の場合、それは失敗しているようです。
GAC でのアセンブリ:
.aspx ページがそれを使用しようとしたときのエラー:

更新: ビルド時にプロジェクトに含まれるように、欠落している .dll に対して「ローカルのコピー」を「true」に設定しようとしました。今、私は別のエラーが発生します:
System.Web.HttpCompileException (0x80004005): c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\geo2\e2a70b87\2b9be05\App_Web_reportviewer.aspx.733fdbe7.njrhyncf.0.cs(254): error CS0433: The type 'CrystalDecisions.Web.CrystalReportViewer' exists in both 'c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\13.0.2000.0__692fbea5521e1304\CrystalDecisions.Web.dll' and 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\geo2\e2a70b87\2b9be05\assembly\dl3\4e808648\047538f8_8e06d101\CrystalDecisions.Web.DLL'

したがって、.dll がプロジェクトにある場合、IIS はそれと GAC の両方を検出し、競合について不平を言うという状況です。アセンブリがプロジェクトにない場合、IIS はどちらも見つけることができません。さらに、エラー メッセージが示す GAC パス (c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web) を開こうとすると、「存在しません」というエラーが発生します。
私は以前よりもさらに迷っています。何がそのような奇妙な動作を引き起こす可能性がありますか?
